Perfectionism, rumination and eating behaviour regulation : are men and women equal in front of psychological processes involved in body dissatisfaction ? / Perfectionnisme, rumination et regulation des comportements alimentaires : les hommes et les femmes sont-ils egaux face aux processus psychologiques impliques dans l'insatisfaction corporelle ?Riviere, Julie 28 November 2018 (has links)
L'insatisfaction corporelle, définie comme la différence entre le corps perçu et le corps idéal (Cash, 2002), a été mise en évidence comme facteur de risque de nombreux troubles et symptômes psychopathologiques. Ainsi, l’une des priorités de la recherche sur l’insatisfaction corporelle est d’identifier les processus psychologiques impliqués dans le développement et le maintien de l’insatisfaction corporelle. L'analyse de la littérature sur l’insatisfaction corporelle, la rumination, le perfectionnisme et l’autorégulation a révélé plusieurs résultats intéressants ainsi qu’un manque d’information dans ce domaine. La plupart des recherches sur le rôle de ces processus dans l'insatisfaction corporelle sont transversales. Ainsi, il a été avancé que davantage de recherche était nécessaire pour examiner les facteurs de risque causaux impliqués dans l'insatisfaction corporelle (Watson et al., 2016). Les objectifs de cette recherche étaient de développer et tester plusieurs instruments de mesure (questionnaire, tâches implicites et comportementales) et protocoles (conception longitudinale, inductions expérimentales) afin d'explorer les relations causales entre perfectionnisme, rumination, autorégulation et insatisfaction corporelle en tenant compte des différences entre hommes et femmes. Les résultats suggèrent des cercles vicieux entre insatisfaction corporelle, rumination et perfectionnisme, ainsi que des différences entre hommes et femmes sur les relations entre ces processus et l'insatisfaction corporelle. De plus, nos résultats concernant les outils de mesure implicites et comportementaux du perfectionnisme comme alternatives aux mesures classiques d’auto-évaluation sont encourageants. Un modèle présentant la manière dont ces cercles vicieux pourraient contribuer à l'insatisfaction corporelle est proposé et des orientations futures sont explorées dans la discussion générale. / Body dissatisfaction, defined as the difference between the perceived and the desired body (Cash, 2002), has been highlighted as a risk factor of numerous psychopathological disorders and symptoms. Thus, one of the priorities in body dissatisfaction research is to identify psychological processes involved in the development and maintenance of body dissatisfaction. The overview of the literature about body dissatisfaction, rumination, perfectionism, and self-regulation revealed several interesting results and also a lack of information in this field. Most of the research on the role of these processes in body dissatisfaction is cross-sectional. Thus, it has been brought forward that more research is needed to examine the causal risk factors involved in body dissatisfaction (Watson et al., 2016). The objectives of this research were to develop and test several measurement instruments (i.e., questionnaire, implicit and behavioural tasks) and protocols (i.e., longitudinal design, experimental inductions) to explore the causal relationships between perfectionism, rumination, self-regulation and body dissatisfaction, while taking into account gender differences. The results suggest vicious circles between body dissatisfaction, rumination, and perfectionism, and differences between men and women on the relationships between those processes and body dissatisfaction. More, our results about implicit and behavioural measurement instruments of perfectionism as alternative to the classical self-report measures are encouraging. A model presenting how all these vicious circles could contribute to body dissatisfaction is proposed and futures directions are explored in the general discussion.

The sex-related effect on copings to negative affectCho, Wan-chi, Valda., 曹韻芝. January 2013 (has links)
Rumination is generally defined as a repetition of a theme in thoughts. Rumination has been consistently associated with psychopathologies. Among these psychopathologies, the relationship between depression and rumination is likely the most widely researched. Rumination was found able to predict onset of depression and duration of depressive symptoms. Rumination was also suggested to be a maladaptive coping to stress and distress, which enhance avoidant coping strategies and then further increase depression. Hence, understanding the neural basis of rumination would shed important insight into the mechanisms underpinning the regulation and dysregulation of emotion that would guide the development of cost-effective interventions.
Study One was conducted to understand the sex-related differences in the rumination subtypes’ relationships with negative affect and avoidance. Thirty-six healthy participants (23 females, 13 males) were recruited in the community. We found a positive association between brooding and negative affect in both males and females. We also found, as hypothesized, a positive association between brooding and avoidance, and a negative association between reflective pondering and depression in females. A negative association between reflective pondering and avoidance was also found in males. However, reflective pondering was found to be positively associated with depression in males in this study. The findings suggest a gender difference in their emotional regulation.
The brain structural correlation with this sex-related behavioral data was investigated through a voxel-based morphometry study. The sex-related difference of rumination subtypes and their relationship with negative affect, avoidance and brain volumes were explored. We found males having a larger gray matter volume over left anterior cingulate than females, and gray matter volume of this region was found to be associated with brooding in the literature. A significant interaction effect of gender and brooding was found over gray matter volume of left lateral parietal, while a significant interaction effect of gender and reflective pondering was found over gray matter volume of the several frontal regions. Consistent with the behavioral study findings, the left inferior temporal, left postcentral and right anterior cingulate were found to be associated with the significant associations between rumination and negative affect found in Study One. We also found the left inferior temporal and right precentral positively associated with brooding and behavioral-nonsocial avoidance in females. This was also found to be consistent with results from Study One.
In this study, the sex-related differences among rumination, negative affect and avoidant coping strategies were found to be correlated to the regional gray matter volumes. These findings do not only help us better understand the neural associates behind the sex-related behavioral differences often discussed and found in previous studies, they also give us further information and direction on the management plans of the emotional and avoidance problems associated with rumination. / published_or_final_version / Psychology / Doctoral / Doctor of Philosophy

Shame and guilt on depressive mood : testing for the mediation role of self-esteem and ruminationMakhanya, Pakate David January 2017 (has links)
The role of self-conscious emotions of shame and guilt on depression is ambiguous, while studies simultaneously investigating shame and guilt suggest that both emotions have strong unique effects on depression, it is however not yet clear which psychological processes cause shame and / or guilt to be related to depression. This study tested the hypothesis that shame but not guilt will be associated with depression, and that this relationship will be fully mediated by self-esteem and rumination. A sample of 246 university students (mean age = 20.39 years; SD = 1.89), completed a survey questionnaire with measures of shame, guilt, self-esteem, rumination and depression. Path analysis was used to analyse the data. The results indicated that shame but not guilt had a strong unique effect on depression, and that self-esteem and rumination fully mediated this relationship. However, guilt had a significant but weaker relationship with depression, and self-esteem and rumination did not mediate the relationship. Recommendations for future research and limitations of this study are also presented. / Mini Dissertation (MA)--University of Pretoria, 2017. / Psychology / MA / Unrestricted

Worry and Rumination: Measurement Invariance Across GenderCarter, Janet A. 01 December 2010 (has links)
The present study examined the factor structure of the Penn State Worry Questionnaire (PSWQ), the Student Worry Questionnaire-30 (SWQ-30), the Anxious Thoughts Inventory (AnTI), the Ruminative Responses Scale (RRS), and the Rumination-Reflection Questionnaire (RRQ). The present study also examined the measurement invariance between men (n = 186) and women (n = 316) in a university sample. Different models for each measure were identified through a review of the literature, and the models were examined through confirmatory factor analyses. The best-fitting models for each measure were retained for subsequent model modification to improve fit and for invariance testing across gender. The results of the confirmatory factor analyses and subsequent exploratory models provided general support for invariance in the configural models, but only the RRQ displayed measurement, scalar, and latent mean structure invariance. Results of the bootstrapped regression analyses indicated that summated scores derived from the exploratory models demonstrated different relationships between anxiety and depression in men and women. Frequency of worry, metaworry, and general anxiety symptoms significantly contributed to prediction of anxiety in men, whereas metaworry, social worry, lethargy, general anxiety symptoms, and health worries predicted anxiety in women. Social worry, metaworry, recrimination, and reflection (negatively) contributed to prediction of depression in men, whereas social worry, metaworry, lethargy, general anxiety symptoms, and social adequacy concerns predicted depression in women.
